So I bought a snail (I think it's an apple snail) for Percy's tank. On the way home, we had to take a very long stop to get fuel, and all in all the snail was in the shop bag for about an hour and a half. When he was in the bag, he was moving around and was stuck to the side, but since I have put him in the tank he has not moved one bit.
Here is a picture of the little guy. I noticed the woman at the Aquatic Centre just yanked him out of the tank and dumped him in a bag of water, obviously not realising that snails are actually sensitive little critters.
Is he dead or just settling in? He's been in the tank for about half an hour.
